Hi Margaret. I'm writing a book on the ways grandmas have fun with their grandchildren, and since you obviously have a lot of fun, I'd love to be in touch with you. Check out my website: www.SallyWendkosOlds.com or my blog: omasally.blogspot.com. It would be wonderful if you could email me at WendkosOlds@alumni.upenn.edu, and I'll tell you more about the book. Best, Sally
